Definitions

  • FIGURE 6 is an SEM of a surface of a UNS N08367 alloy after undergoing a treatment that enhances corrosion resistance and which is an embodiment of the method of the present invention, and after being subjected to the ASTM G 150 test;
  • TC Cor 2 crevice test To compare the difference in the corrosion resistance capabilities of a UNS N03867 alloy processed in a conventional manner with the same alloy that has undergone a treatment that is within the method of the present invention, alloy samples were tested to measure CCCT utilizing a TC Cor 2 crevice test. This test is often specified when steel products are being qualified for severely corrosive applications.
  • the TC Cor 2 test is a bolted multiple crevice test which will be generally familiar to one of ordinary skill.
  • the TC Cor 2 test in particular, entails exposing a steel sample to a 10% FeCl 3 -6H 2 O solution for an exposure time of 72 hours.
  • Delrin washers in accordance with the ASTM G78 specification, are bolted to the test sample to create artificial crevices on the sample surface. All TC Cor 2 testing used herein was performed after applying a torque of 58 inch-lbs to fasten the washers to the samples surfaces. To determine the threshold temperature for crevice attack, samples were tested over a range of temperatures. With plate samples, crevice attack is considered present if the weight loss of the sample is greater than 0.0002 grams/cm 2 or if the depth of corrosive attack is greater than 0.0015 inches. Historically, the expected results of the TC Cor 2 for austenitic stainless steels could be predicted based on alloy composition.
  • TC Cor 2 crevice testing was performed on samples of UNS N08367 steel processed in a conventional manner, including a mill anneal and an acid cleaning under typical processing conditions.
  • the results of the TC Cor 2 testing, at temperatures ranging from 32.2°C (90°F) to 46°C (115°F) are set forth in Figure 1(a) through 1(d).
  • failures were experienced at all temperature measurements, including those conducted at temperatures as low as 32.2°C (90°F). Those results are consistent with what would be expected by the results of Equation 2, above.
  • the ECPT is a sensitive method of ranking an alloy's resistance to chloride pitting.
  • the test includes holding steel samples at a constant potential of 700 mV (vs. SCE) while the temperature of the specimen and test solution are increased at a rate of 1°C per minute.
  • the measurements reported herein were performed in a Gamry Flex Cell using the Gamry CMS 110 Critical Pitting Test System.
  • the electrolyte used in the testing consisted of 1 M NaCI and the cell was purged with 99.99% nitrogen gas during testing.
  • the ECPT is defined as the temperature at which the current increases above 100 ⁇ A/cm 2 and stays above this threshold current density for 60 seconds.
  • the acid cleaned mill surface shows the least resistance (lowest ECPT).
  • the corrosion resistance is improved.
  • the samples used to w obtain the ECPT results were examined by a scanning electron microscope to see if the initiation sites for corrosive attack could be identified.
  • the attack on the surface of the acid cleaned sample is shown in Figure 5.
  • the initiation sites consist of regions that are preferentially attacked, thereby resulting in a very unusual etch pattern.
  • the morphology of the attack suggests the presence of a more active surface condition that serves as the weak link in the corrosion resistance of the steel.
